To all whom it may concern:

Be it known that I, WILLIAM ZAoHow, a citizen of the United States, and a resident of Racine, county of Racine, and State of Wisconsin, have invented certain new and useful Improvements in Baling-Presses, of which the following is a full, clear, and exact description.

The invention relates to baling presses and seeksto provide'improved mechanism by which pressed bales of straw, hay or the like may be rapidly formed. The invention consists in the features of improvement hereinafter set forth, illustrated in the pre-' ferred form in the accompanying drawings and more particularly set forth in the appended claims.

In the drawings, Figure 1 is a view in elevation-of the left-hand side 'of the improved baling machine. Fig. 1 is a view the line ear-22 of Fig. 20. Figs. 23 and 24 ar'detail sections on the lines 23-23 and 2424 ofFig. 22. Fig.25 is an end view of the knotting twister. Fig. 26 is a detail view on the line 2626 of Fig-22.. Figs. 27 28 and 29 are plan views of the linotting twister and knife for severin the wire, illustrating different positions 0 the parts. I

The main frame is mounted upon the axles 10. and 11 of the front and rear wheels (see Fig. 4) are mounted upon the ends, of the rear axle 11 and: upwardly extending vertical side plates'15 and rearwardly/er veyer that delivers the straw, hay or, the like to the machine.

A pair of-cast metal upright brackets 25 are secured to the rear ends of the side plate 16 and the upper ends of these brackplates 29 and 30 extending between side bars 31 and provided with strengthening angle bars 32. Endless belts 33 connected by cross strips 34 pass over pulleys 35 and 36 (see Figs. 1 and mounted on shafts 37 and 38 at the opposite ends of the conveyer. The conveyor is preferably divided into sections, the rear section bein mounted upon the front side plates 17 o the machine and the front section having a hinged connection 39 with the rear section. conveyer are provided with flaring side plates 40 extending above the floor 29 over which the hay or straw is carried and held in position by bars 41. The'bars 41 of the outer section are removably seated within sockets 42, so that the side plates 40- of the outer section can be removed and the latter swung upwardly and rearwardly onto the rear section of the conveyer to thereby decrease the length of the machine when it is not in use.

As the straw, hay, from the upper rear or the like is delivered end of the conveyor it passes over a downwardl rearwardly inclined guide plate 43 and etween a pair of upper and lower feed rollers 44 and 45 that are mounted respectively upon the trans verse shafts 46 and 47.. The transverse guide plate 43 extends between and is fixed to the vertical side plates 15 of the machine and the shaft 47 is journaled in these side plates. The shaft 46 side plates 15 (seeFigs. 1 and 3) an'd is journaled in the rear ends of a pair of arms 49, the rear ends of the arms being hun upon the shaft 37. The upper feed roller is thus free to rise and fall, but itis forced downwardly to press the layer of straw between it and the lower feed roller by a spring 50 (see Figs. 3 and 5) which extends between the rear end of the adjacent arm 49 and a br cket 51 on the adjacent side plate 15. To as at in properly delivering the straw to the ced rollers, a short supplemental conveyer is arranged above andbehind the rear end of the main conveyer This supplemFntal conveyeij' is dowii'w rdly and rearidly incline x#tovvard the feed rollers 44 at d 45 and co prises ah ndless belt 52 having cross str a pair of pulle s 54 and 55. which are carried upon a pair of transv rise shafts 56 and 57, the shafts being joutna'ltd. in suitable hearings in the side plates 5g i- The feed rollers and the upper and lo driven from a main dri je shaft 58 which extends transversely between and is jour naled in suitable bearings on; the vertical side plates 15 and which is provided at one end with a pulley 59 adapted t o receive a belt from an engine or other suitable source of power. At the opposite end, the main drive shaft is provided with a pinion 60 (see Figs. 3, 15 and 18) which meshes with a gear Both sections of the or shou extends through slots 48 in the ps 53 thcpbn passing over ver conveyers are- (see Figs. 15 and 16') which is pivoted upon the gear 64 and which is normally held by a spring 66 in engagement with a cam lii der 67 on the hub of the The drive shaft 37 of the main conveyei is provided at its right-hand end with agear 68 and is driven from the shaft 47 of the lower feed roller through the medium of an .idler pinion 69 which is journaled upon a suitable bracket on the adjacent side plate 15 and meshes with the gears 64 and 68. The

gear 63 f gear 68 also meshes with a gear 70 fixed to the drive shaft 47 of the upper supplemental conveyer (see Figs. 3 and 15). At the lefthand side of the machine the shaft 37 is provided with a gear 71 which meshes with the gear 72 on the shaft 46 of the upper feed roller 74. By the gearing described, the main and supplemental conveyers and the feed rollers are rotated during the operation of the machine. At intervals the feed of straw, hay or the like to the machine is arrested, as hereinafter described, by disengaging the clutch dog 65 to thereby disconnect the operating mechanism of the conveyers and feed rollers from the main drive shaft. Preferably, as shown in Fig. 5, the upper feed roller is provided with ribs or corrugations.

From the feed rollers 44 and 45 the layer of straw passes over a transverse guide bar or plate 73 and beneath a transverse angle bar 74 and thence between a pair of guide rollers-75 into the baling box at the rear orti'o'n of-the machine. The transverse ,ars 73 and 74 extend between and'are fixed to the side plates 15 and the guide. rollers 75 are mounted on transverse shafts 76 that are suitably journaled in these side plates. These rollers are located, as shown, between the segmental plates 27 and 28.

The baling x comprises transverse upper and lower plates 77 and 78 which are connected at their edges to angle bars 79 and 80 and are provided on their outer faces with strengthening angle balis 81. Side plates 82 depend from the bars 79 and cast metal brackets 83 and 84 are securely bolted to the front and rear ends of the bars 79 and of the side plates 82. The brackets 84 are provided with lateral projecting trunnions 85 which are journaled in the upper ends of the brackets 25 and which are connectedto the rear ends of the brace bars 26. brackets 84 are connected beneath the hot- The lower ends of the tom plate 78 b a transverse rod 86. a The lower ends of t e brackets 83 are connected beneath the bottom plate 78 by a transverse rod 87 and a transverse shaft 88. The lower plate 7 8 of the box is pivotally connected to the lower ends of the brackets 83 by bolts 89 that extend through the brackets and through the forward ends of the side bars 80 of the lower plate. The; rear end of the lower plate is connected tothe upper plate by a pair of rods 90 extending throughtwo portions .of the side of the angle bars '81.. prings 91- are coiled about the upper ends or these rods and extend between the u per angle bars and a pair ofhand wheelswhich are'thregded upon the upper ends of the rods '90. dBy ran ement the upper and lowei.-plates of the aling box are yieldinglyspringpressed upon the bales at the rear end thereof to resist the movement of the bales therethrough and so that the straw or haymust be forced at the lower of the baling box.

The'shaft 93 is provided at the right-hand side of the machine with a" gear 96" which meshes with the pinion 60 on" the main {drive shaft 58 (see Fig. 3). 'By this mech- 5anism the baling 'box is constantly oscil- :the machine. The rear e lated up and down durin the operation of es of the vertical I side plates 15 of the-frame and the rear faces of the transverse plate castings 27 and 28 attached thereto, are coincident and concentric with the pivotal axis of the baling box. The upper and lower side bars 7%.and 80 of the latter are connected b trans-- verse angle bars\81 and 81'' and; the upwardly and downwardly projecting flanges of these bars move closely adjacent the segmental surface of the transverse plates 27 and 28 The edges of the side plates 82 of the box (see 12' and 14) move closely adjacent the segmental edges oftheside plates 15 and a'pair-of segmental guide bars 97 secured to the outer faces 'of the side plates overlap 'the-forwardsidejedges of 66 against lateral movement.

the baling box, as most clearly shown in Fig. 14,; The-cast metal brackets 83 at the forward-end of the'box have forwardly projecting lugs 98 fixed thereto which overlap the outer faces of the segmental guide bars 97. By this arrangement, the forward end of the box is properly guided andheld this arlatter is oscillated. The shafts 76 whereon the rollers are mounted are provided on their outer left-hand ends with gears 99 (see'Fig's. 1 and 10) and these gears are engaged by a segment rack 100 mounted on the forward end of the baling box at its left-hand side. The bracket 83 on this side of the box is provided with a projecting portion (see Fig. 14) to which the segment rack -10() is connected. thelike is fed in a web by the rollers 44 and 45 over the guide plate '73 and between the rollers 75. The web of material passes between these rollersand into the forward end The straw, hay or 1 of thefbalingjbox-and is folded back and forth therein as the box is reciprocated, as indicated in dotted lines in Fig. 12. The oppositely rotating'rollers 75 guide the web of. mater1al into the box and assist in folding it back and forth therein. That is to say, asthe box moves up the \web of mate-'- rial passesaround the upper roller 75 and when it moves down, it is guided around'the lower roller. The rollers and the segmental plates '27 and 28 also act to compress the material within the forward end of the box as the latter is reciprocated. Preferably,

also, the rollers 75 are provided each with a row of beveled teeth 101. These teeth are provided. with beveled faces and radial faces and are oppositely arranged, as shown. When the box is moving up, the teeth-of the pper roller engage the web and tend to orce the material upwardly toward the upper portion of the box. When the box is moving down, the beveled faces of the teeth on the upper roller are moved over the web of material, so thatthe movement ofthe latter-is not affected thereby, but the abrupt or radial faces of the teeth on the lowerroller then engage the web ofstra'w, hay or the like and force it down toward the lower portion of the box.

Thebaling'box is open ended and is pf' sufiicient length to receive two or more bales,

as indicated in dotted lines in Fig. 5, and

the upper and lower sections of the box are forced together at their rear ends by the springs 91 to resist the movement of the bales.

through {the box. By this arrangement,-the

' previously formed bale acts as an abutment against which. the next bale is formed. I The feed rollers 44 and 45 and the guiding and compression rollers 75 act to force the web of material "into the open end of the box and against the previously formed bale, the, web

I of material being foldedb'ack and forth in the box, as the latter is oscillated. The feeding of the material into the box also serves to force the finished bales through the box and automatically discharge them from its open rear end.

The segmental guide plates 27 and 28 are provided with guide-ways 102 (see Figs. 10, 11 and 12) for the wire carrying needles. These guide-ways are, preferably cast in piece with the plates 27 and 28 and are formed upon the rear faces thereof behind guiding slots 103 in the are also provided on t eir rear portions with strengthening flanges 104. The lower edge of the plate 27 i and the upper edge of the plate 28 extend closely adjacent the vperiphery fthe rollers 75 and the edges 'of the plates are provided with slots 105 (see Fig.10) to permit the passage of the beveled teeth 101 of the rollers therethrough.- To permit the passage of the wire carrying needles in front of the inlet end of the. baling box, .-the rollers 74 are fprmedin. separate sections which are keyed to .the'

shaft 76 and are separated by .collars'106 on the shaft to form spaces between the sections in line with the needle guide-ways? and slots "102 and 103 in the segmental plates,

The sections of the'rollers 75 are preferabgiyi'.

S- 'in a socket ofa bracket 134 on the adjacent hollow and are provided .with ends or liea 1071havin inwardly projecting hubs 108 through w? p rollcrsf to the shaft 76. The periphery-of each section of the rollers is provided with:

openings 110 in line with the keys 109, so that the parts can be readily assembled o1; disconnected for repairs.

."When sufficient material is fed into the box to 'form a bale, the operation of the feeding conveyer and of the feed rolls 44 and 45 is arrested and the web is cut oil by a knife 111 which reciprocates vertically be-.

tween the feed rollers 44 and 45 and the guiding rollers 75. The knife 111 is fixed at its upper edge to a bar 112 and the ends of these parts extend through slots in the side plates 15 of the frame, suitable guides 113 being secured to the outer faces of the plates 15 at the edges of the slots. The knife is suspended'from a transverse crank shaft 114 journaled in the side plates 15. C01 lars 115 (see Fig. 13) on the crank arms of this shaft are connectedby horizontal pivot bolts 116 to couplings 117 on the upper ends of a pair of link rods 118. The couplings 119 on the lower ends of the rods are hori-, zontally pivoted to brackets 120 outhe'knife bar 112. The left-hand bracket 120 is provided with an upwardly projecting lug. 121

which is connected by a link 122'150 a bracket construction illustrated three wires are tied 123 fixed to the inner face of the adjacent side plate 15. When the shaft 114 is rotated, the knife 111 is depressed to sever the web passing from the feed rollers 44 and 45. In this lowermost, po sition, the knife engages lplates. The plates .flange 132 on t movement of "the knife shaft 114, when the iich keys 109 extend to secure the 4 a transverse wooden strip 124 Set into the guide plate 73 (see Fig. 12). During the downward movement of the knife toward the wooden strip, the link 122 serves to shift the knife lengthwise, so that :it operates with a draw cut, and thereby serves to effectually sever the web of material.

The knife operating shaft 114 is provided at' its right-hand end with a pinion 125 which meshes withthe gear 96 0111 the shaft 93 and is constantly rotated at high speed thereby.- This pin1on 125 is, loose on the shaft and the latter is provided with a clutch disk 126 (see Figs. 15 and 18) fixed thereto.

A clutch dog 127 pivoted on the disk is arranged to engage a lug or'shoulder 128 formed-upon the hub of the pinion 125. Normally the knife shaft 114 is held statihi ary with the clutch dog in disengaged position by a trip arm 129 that is ivoted upon a bracket 130 on the adj acen't sidhplate 15.- This trip'normally holds the clutch dog 127in disengagedposition with a laterally projecting pm" 131 thereon held against the inner periphe of a laterall projecting ile disk 126. T e b'jackward clutch dog is indisengagedposition, is prevented bya stop pawl 133 which is mounted V and is adapted to cooperate with a shoulder 136 thereon to prevent the backward 'movement of the knife operating shaft 114. The

knife shaft is arrested by the clutch tripf ping arm 129. with the knife uplifted and the'crank arms of the shaft 114 in front of the .center of the shaft. When the trip arm 129 is shifted to release the dog, the latter is forced by a spring 127 into engagement with the shoulder 128, so that the shaft 114 is rotated in the direction indicated by the arrows in Figs. 5 and 15. Moreover, inasmuch as the-crank arms are normally slightly in front of the axis of the shaft 114, the downward movement of the knife is assisted by gravity and the knife arts to effectually sever the web of straw by its engagement with the wooden strip 124. As soon as the parts are restored to normal position, theabout each bale and for -this purpose three,

wire Icarrying needles 137 are provided.-

These needle afe formed of segmental flat bars and arranged to slide through the guide-wa s and slots 102 and 103 of the segmental p ates 27 and 28. The lower ends of the needles are provided with offset ortions that are secured toa pair of crossare I38 and 139 and these cross-bars extend bej tween the-lower ends of a pair of arms 140, the upper ends of which are hungupon the trunnions 85' of the baling box. A needle operatin shaft 141 is journaled in brackets '10.?142 out em per front end of the balingl hpx. The eh of this shaft are provide a crank'arm 143 and a pin 143 on a "Ett 200 which we .poi nected by links or rods-144 to the side 140. When the fshaft'141 is rotated throiigh a single revo- 'l'utiom-the needles 137 are raised and lowered to Carry the wires in front of the box. Guide strips 145 are secured to the sides of the needle bars adjacent their outer edges and a number of rollers 146 are mounted upon-xthe sides of the bars. Each of these rollers is preferably arran ed between the bar 137 and a plate lug 14 secured to the guide strip 145, the roller being 'ouraraled upon a stud 148 extending throng the bar a and the plate 111 rpllers 149 are a so mounted between supggrting lugs 150;.that depend from the cross- "r139. 3 0 The tie j'wire is carried on'the machine in a seriesqof. cams. These cans comprising cylindrical sheet metal body-portions 151 havinhem'jheads 152 and the heads are provi ed with central openings therein. The

cans are mounted upon'a shelfl53 that is carried upon the transverse bar 24 with the inner ends of the cans against a vertical plate 154 alsd fixed to the transverse bar 24 and connected to the shelf 153 by triangular end plate 154. U-bolts 155 extend over the upper portions of the cans and through an angle bar 156 at the upper edge of the plate 154. By loosening the nuts on the U-bolts, the empty cans can be removed and full cans placed in position upon the r machine. A series of gu1de'pie'oes-157 are. v fixed to the plate 154 and the inner portion '.of the guide piece is adapted to extend within the central opening of thejinner head 152 of the can. This guide -is provided witha 1 flarin rounded opening throughwhich the "wire rom thecan passes. g

- The-wire a is coiled snugly within the can in a series of cylindrical layers and-the lay- '55 ers aresuccessfully withdrawn from the can beginning with the innermost layer ofwire. By this 'arrangement,. it is unnecessary 'to providereels and the wi-r g the machines and there; twisting of the wire/ no kinking or t is- Withdrawn.

With rotating reels, it is difficult to overcome the momentum imparted thereto as the wire is withdrawn. The cans have longitudinal openings 151 in their sides so that the may be readily inspected to determine w ether or not the wire therein is exhausted.

The wires a pass from the cans down beneath the guide rollers 149 and thence upwardly-through the needles and between the guide rollers 146 and guiding strips 145 thereon. From the ends of the needles the wires pass across the open inlet end of the baling box and through a series of notched guide'lugs 158 (see Figs. 20 and 22) secured to the front edge of the upper plate 77 of the baling box between spaces formed in the angle bar'8l -fl The free ends of the wires are gripped by the knotter mechanisms mounted upon the upper front portion of the baling box.. As the straw, hay or like material is forced into the front endof the .laaling box, thewires are moved rearwardly therethrough and are thus passed around the upper, lower'and rear sides of the bale. As this occurs, the wires are drawn out of the cans and through the needles. -When sufiicient material is forced into the end of the box to form a bale, the; needles are shifted and the wires carried around the forward side of the bale. t

Each of the three knotter mechanisms is carried by ;a cast metal bracket 159 which is hung at its upper rear end upon the shaft 141 and extends downwardly and forwardly therefrom. The lower forward ends of'these' brackets are secured -to a transverse angle bar 160 which extends between the side bracket 142 in which the shaft 141 is journaled. The knotter mechanisms are operated by a series of combined cam and gear wheels 161 that are fixed to the shaft 141. This shaft is normally stationary, but is rotated through a single revolution at each operation of the machine to tie the wires about the bales.

Each the knotter mechanisms is provided wi h a twister having two hook-like arms 162 and-163 mounted upon excommon hub which is connected by a pin 164 to'the lower endof a-shaft 165 which is i'ournaled so longias most clearlyfishown in' F g. 25, with. a .notch orguideway '168for t e tie wire; The ,Shaftlfiaj is longitudinally 'mpvable tot-shift the twister to and from the plate 166. For this purpose, the inner end of the shaft is provided with a loose sleeve 169 held in place thereon by a collar 17$) and the sleeve is provided with projecting p as 1.71 which engage notches in the sides of a yokelever 172. The inner endof the lever is provided with a roller 17 3 which engages an internal cam shoulder 174 on the wheel 161. The outer end of the yoke-lever engages a bolt 175 which extends through a lug 176 on the bracket 159 and a spring 177 on the bolt tends to hold-the lever a ainst the lug. By this arrangement, the siaft 165 is longitudinally shifted as the wheel 161 is rotated to yieldingly press the twister against the plate 166 and thereby clamp the wire between these parts, as hereinafter described.

The inner end of the shaft is also provided with a gear wheel 178 which is keyed to the shaft, but which is arranged to permit the longitudinal movement of the latter therethrough. The hub of this gear wheel is provided with a flange 179 which is flattened at diametrically opposite points. The fiattened portions are arranged to enga e segmental ribs 180 and 181. upon the face of the wheel 161 to thereby hold the gear and the knotting twister against revolution. Two segmental sets of gear teeth 182 and 183 are arranged between the ribs 180 and 181 and by engagement with the teeth of the gear 179 serve to rotate the shaft 165 and the knotting twister thereon. The teeth 182 are arranged to impart a half revolution to the twister and the teeth 183 of the twister are arranged to impart two and a half revolutions thereto.

A hook-shaped knife 185 is arranged against the inner face of the plate-1.66. and the hub 186 of this knife is keyed to a sleeve 187 which is arran ed withi ithe'bore of the sleeve portion of t e bracket 159 and about the shaft 165. A beveled gearwheel 188 loosely mounted upon the shaft 165 is pro vided with a hub which is permanently clutched to the sleeve 187 to rotate the sleeve and knife 185 connected thereto. The beveled gear 188 is provided with a flange 189 having a flattened portion on one side thereof whlch is arranged to be engaged by a rib 190 on the face of the wheel 161 to hold the knife :1 ainst movement. A segmental series of beve ed gear-teeth .191 on the face of the wheel are adapted to engage the gear 188 and rotate the knife through a single revolution. Y

Mounted on the sleeve 187 against the inner face of the knife 185'is a spring-held clamp plate 192. One end of this plate is provided with an outturned ortion 193 which engages the plate 166. .he opposite end of the plate 192 is spaced apart from the plate 165' by a collar 194 mounted on a Springs 196 located within suitable sockets in the lower portion of the bracket 159 en gage the plate 192 and press it toward the knife. The plate is provided with a notch or guideway 197 for the wire (see Fig. 26) and the spring 196 at this end of the clamp plate is preferably provided with means for adjusting its tension, such, for example, as an adjusting bolt 198 (see Fig. 22) which is arranged to engage the inner end of the spring.

When'sufiicient material is fed into the box to form a bale, a single revolution is.

imparted to the shaft 141 to thereby ra= and lower the wire carrying needles 137 and. operate the knotting twisters. knotter mechanism is idle, the free end of each wire (1 extends over the arm 162 of the .knotting twister, over the plate 166 and over the knife 185 and thence downwardly through a notch or slot 199 on the inner side of the knife. The free end of the wire is thus gripped between the inner side of the knife and the clamp plate 192 which is spring pressed against the knife. This posi tion of the parts of the knotting mechanism is shown in Figs. 20, 22, 25 and 26. The gear segments 182, 183 and 191 on the wheel 161 are so arranged that as the latter is rotated the segment 182 will first act to impart a half revolution to the knotting twister and the gear segment 183 will thereafter impart two and a half revolutions to the twister to return it to normal position. The segment 191 is so arranged that it operates the knife after the twister has been given a half revolution by the segment 182, but, before the segment 183 acts on the twister, the segment 191 will advance the knife a half revoluand the remaining half reyolution of the knife taking place together with the movement of the twister.

The first half revolution of the twister effeeted by the gear segment 182 brings the arm 163 thereon over the free end of the wire a so that the free end is then grippedv between the and 163 and the end plate 166, as shown in Fig. 27. V The segment 191 then moves the knife, the twister remaining stationary until the knife has completed a half revolution. By this time the needle has brought the other end of the wire upwardly and in front of the bale. This position of the parts is shown in Figs. 21- and 28. The knife and twister then move together so that the wire is cut oil by the operation of the knife against the inner face of the plate 166,

- and the end of the tie wire about the bale is gripped by the arm 162 of the twister. After one revolution of the knife its movement is arrested and a new free end of the wire a is gripped between itand the spring-held elampplate 192, as shown in Fig. 29. The twister. however, is given two additional When the cylindrical lug .195 of the bracket 159. ro'volutions and the ends t of the tie about 120 the bale are twisted together, as shown in Fig. 29. At the end of the twisting operation, the internal cam shoulder 174 permits the outward movement of thg shaft 165 and of the knotting twister armsffl62 and 163 to I release the tie wires, and the need es are then mounted upon a short shaft 205 on the upper portion of the box. A sprocket wheel 206'fixed to the gear 201 is driven-by a chain 207 that passes over a sprocket wheel 208 loosely mounted upon the stub shaft 62 (see Figs. 3 and 17 A brace bar 209 extends between the stub shaft 62 and the ri ht-hand trunnion 85 of the baling box to re ieve the. parts of the strain incident to the tension on the chain207. A chain tightening wheel 210 is adj ustably mounted on the brace bar 209.

The hub of the sprocket 208is provided with a flange 211 having a notch 212 therein which is arranged to be engaged by a clutch dog 213 which is eccentrically pivoted upon the gear 61. The gear 61 is also loosely mounted on the stub shaft 62 and is con tinuously driven during the. operation of the machine by t e pinion 60 on the main drive shaft. A spring 214 extends between studs 215 and2l6 which are respectively pivoted against a shoulder 220 formed on the face of the gear 61. The shift of the dog into and out of operative position is controlled b a trip arm 221 mounted upon a shaft 222 t at is gournal'ed in-a suitable bracket on the adjacent side plate 15 and projects laterally therefrom. The end of the trip arm 221 is provided with an inwardly projectingseg mental rib 223 which is arranged to 006pera'te with an outwardly projecting, triangu-" lar lug 224 on the clutch dog 213 to shift the clutch dog in to and out of operative position. The sha t 222 is also provided-with a trip arm 5,,p'hich is arranged to engage and rele ithefclutdi dog throw the feed mechanism out of operation.

6'5 and thereby The trips 129,221 and 225'for the clutches that control the knife, the tying mechanism and the feeding mechanism are all actuated by a common shifter which, in the form shown, comprises .a four-armed member mountedupon a stub shaft 226 on the. righthand side plate 15 (see Figs. 3, 15 and 17). One arm 227 of the shifter is connected by a link'228 to an arm 229 on the shaft .222. lug 230 is adjustably connected to the slots the link. This lug is arranged to 228 by bolts 231 extending through be engaged by a shifter actuating member,

which comprises a bar 232 slidably mounted 'in guideways formed in the bracket 83 on the right-hand side of the baling box. A compression spring 233 extends between the box and the rear end of the actuating bar 232 and holds the latterin normal position with a stud. 234 thereon against a portion of the bracket. "In this normal position of the parts the forwardend of the. actuating bar 232 doesnot engage the lug 230 11 the shifter as the baling box is oscillated, but the bar is moved to engage the hi when sufiicient'inaterial. has passedinto he box to form a bale. This is efiected by a toothed wheel 235 (see Fi 3, 14 and 19) which is mounted upon; fiacket 236 on the outer face of thesid pla-te 82, of the'baling box, the teeth of the wheel' 'bein arranged to extend through a slot 237 in t eplate. The teeth 'of the wheel are thus engaged by the straw, hay or like material in the box, and the wheel is rotated by the movement of the material through the box. When sufficient material has passed into thev box. to form a bale, a lug 238'on the upperfaceof the wheel engages a shoulder239 on the shifter actuating bar 232 and forces the latter for- Wardly against the tension of the spring 233, so that at the end of the next upward movement of the baling'boxthe forward endof the bar will engage the lug 230 and oper ate the clutch shiften. I J Another arm240 on-"the, clutch shifter pivotally engages a stud'1241 at one endof a spring 242. v engages astud 243 which is pivoted upon the bracket 51. This spring is arranged to shift on the opposite sides bf a line be-- tween the shaft 226 and the ivot 2440f the stud 243 and thereby ho d the fourarmed shifter in either one of two positions, as shown in Figs. 15 and 16.

At this time the dog 215 has just passed the tappet 246, so that the shifter remains in the position shown in Fig. 16 for a full revolution of theshaft 93 and for a complete oscillation of the baling box. At the end of this, one revolution 0 the dog 245 engages the tappet 246 and the position shown in Fig. 16 to the normal. position the arm.

The fourth arm 248 of the shifter is provided. with a tappet 249 adjustably connected thereto and which is arranged to engage a dog 250 pivotally mounted upon the heel end of the trip arm 129. A spring 251. normally presses the tail of the dog 250 against a stop lug 252 on second spring 253 extends between the arm and the bracket 130 and holds the trip arm in normal position with a shoulder 129 thereon engaging the periphery of the clutch disk 126. When the shifter is operated, the tappet 2=Jt9 acts upon the dog 250 to lift. the trip arm 1.29 out of engagement with the clutch dog 132. The shaft 114 is then rotated to operate the knife, as de- Scribed. The tappet 2l9 moves past the dog 250, as shown in Fig. 16, so that the triparm 129 is in position to disengage the clutch dog 127 after a single revolution of the knife operating shaft. On the restoring movement of the clutch shifter the tappet 249 moves idly past the dog 250.

The clutch dog which controls the op eration of the feed mechanism is normal y in operative position, as shown in Fig. 15. When the shifter mechanism is moved by the actuator bar 232, the trip arm 225 is shifted to the position shown in Fig. 16, with a shoulder 225 thereon against a and the clutch dog 65 is disengaged to arrest the operation of the feed mechanism and hold it idle until the tying mechanism completes its movement. In its disengaged position, a pm 65 on the dog engages the inner face of the flange, 64 llhe l'utch dog 220 which. controls the op eration of the wire tying) mechanism is normally out of operation, at when the clutch shifter is moved, the trip arm 221 occupies the position shown in Fig. 16, so'that the segmental flange 223 thereon engages the lug 224 on the dog and shifts it inwardly so that the dog'engages the notch 212 in the hub of the sprocket 207 and the clutch thus.

the shaft 93,

sition, the trip arm 221 is moved into the position shown in Fig. 15, with the segmental Hange 223 against the hub of the sprocket 207. It then engages theinner face of the triangular lug 224 and thus restores the clutch dog 213 to the normal position shown in Fig. 15. I

By this arrangement, the, feed mechanism, the knife mechanism and the tying mechanism are controlled by the movement of the material through the open ended baling box. The feed mechanism is normally in o oration While the llhife and the .tying mechanisms are normally held out of operation. When suflicient material passes into the'box to form a bale, the clutch shifter is 013 rated to throw the feed mechanism out of operation and the knife and tying mechanisms into operation. A the end of the tying operation, this clutch isshifted to disengaged position and the clutch of the feeding mechanism is recngaged to feed the material and form the next bale. Upon the u ward movement of the wire carrying nee les, :1. projecting arm 144 on one of the connecting rods 144 (see Fig. 13) engages the end of the shifter actuating bar 232 and lifts ity to disengage its shoulder 239 from the lug 238 on the controlling Wheel 235. The bar can rock sufliciently in its guides to permit this movement. The spring 233 then returns the bar to its normal, inoperative position and the wheel 235 is then free to be rotated by the movement of the material through the baling box to again shift the bar when suflicient material is compressed into the box to form another bale.

In transporting the machine, the b lling box is held elevated to hold the wire carrying needles well above the ground by a U catch 255 (see Fig. 2) which is pivotally mounted upon the end of a bar 256 projecting from the adjacent side plate 15 and which catch is arranged to en e one of the spokes /of the pulley 59. race bar 257 extends between the plate .15 and the bar 256. When the machine is in operation, the catch'is turned back into the position shown in dotted. lines in'Fig. 2. The front part of the machine frame is elevated above the front aale and is so connected thereto that the front Wheels can be swung beneath the frame for convenience in turning and also for moving the of the way in operating the machine and in operating the machine the tongue will not interfere with free access to the front end of the conveyor. The size of the bales can be regulated by substituting a larger or a, smaller Wheel or the Wheel 235.

If it is desired to highly compress the hay or st-raw, additional means are provided for resisting the movement of the bales through the open-ended box. This additional means tongue of the front axle outv
